Pin Brazing Machine

The Pin Brazing Machine (also known as a Soldering Machine for cathodic protection applications) is a specialized portable welding device used to create safe, low-resistance electrical connections between copper cables and steel structures such as pipelines, storage tanks, ships, and rebar .

Unlike traditional arc welding or exothermic (thermite) welding, pin brazing uses a silver-based alloy solder that melts at approximately 650°C (1200°F), bonding the cable lug to the steel surface without melting or damaging the base material . The process is battery-powered, making it ideal for remote field locations and hazardous environments where open flames are prohibited .

This technology is widely used in the cathodic protection (CP) industry for attaching test station cables, sacrificial anodes, grounding connections, and pipeline bonding jumpers
